This code will help produce the three visuals that are going to be a
part of each equity tracker indicator webpage: regional map (tract
level) of most recent data, chart of the most recent data, chart of
trends over time.
If the indicator is available through a tract-level data
set. Getting the data to a workable version may require some
data transformation. To explore, clean, transform, and generate a final
data set, please use the data-gen-tract-template. This script
will generate an .rda for the map and an .rda for the charts. These data
sets will be loaded in before the data visualization code.
The rate of incarcerated individuals in Washington State prisons per 100,000 residents by census tract, based on each incarcerated person’s last known address. Understanding where incarcerated individuals come from can help us understand which communities are disproportionately impacted so better policies can be created to change negative outcomes.
To map data in this form, there should be a value corresponding to each census tract. Depending on the year or source of the data, this could be about 700 rows for data at the 2010 census tract resolution, or about 900 rows for data at the 2020 census tract resolution.
The map scale has been adjusted to the natural log of the rate to make the map colors meaningful.

This dataset first became available in 2020 due to a change in
Washington State law requiring the Department of Corrections to report
last known addresses for people incarcerated in state prisons during the
2020 Decennial Census. At this time, 2020 is the only year available and
it is unclear if this data will be available again after the 2030
Decennial Census.
